Abstract: 330,714. Woodhead, G. A., and Sanders, T. H. May 6, 1929. Axle-trucks and bogies; springs, arrangement of.-In a railway or-tramway vehicle bogie of the kind in which the weight of the body is distributed between the centre and side bearings by means of springs associated with transverse pivoted levers, the levers are so arranged that, when the body tilts to one side and part of its weight is thereby transferred to the opposite side, the position of the centre pivot with respect to the outer ends of the levers remains unaltered. In the construction shown the weight of the vehicle body is distributed through a centre bearing 2<a> and side bearings 8 to a swinging bolster 2 supported from the frame 4 by pivoted links 7. The centre pivot pin 3 is anchored to an inverted laminated spring 5 connected to the ends of transverse levers 6, which are pivoted at their outer ends to the bolster and at intermediate points to the links 7. Thus, if a rolling movement to the left occurs as illustrated in Fig. 7, the links 7 effect a displacement of the bolster and vehicle body to the right, while the relative position of the pin 3 and outer ends of the levers 6 is unaltered. Other arrangements are described in which the bolster and swinging links are dispensed with, in which coil springs are disposed between the outer ends of the levers 6 and the side bearings, and in which the laminated spring 5 is replaced by coil springs and spring beam.

Title: Improvements in or relating to internal combustion engines of the liquid fuel injection type
Inventor: RICARDO HARRY R
IPC: F02B19/08
Filed: 1933-05-15
Abstract: 421,275. Oil engines. RICARDO, H. R., 21, Suffolk Street, Pall Mall, London. May 15, 1933, No. 14011. [Class 7 (iii)] The combustion chamber of a compressionignition engine is formed in one or more parts which are separated by an air space from an outer casing or pocket. Air from the cylinder enters through an inclined or helical passage and rotates about an axis about which the combustion chamber is circular in crosssection. An injection device is located in a position remote from the axis and discharges fuel substantially parallel to the axis. As shown in Fig. 1, a cylindrical combustion chamber J is formed by recesses in plug-like members E, G. The chamber communicates with the cylinder through a passage E<2>, and a fuel injector is located at K. In a modified construction, a cylindrical combustion chamber is formed in a liner spaced from the walls of the pocket and having its axis vertical. A fuel injector, disposed in the end wall of the pocket, discharges on to a plug so that no fuel is directed towards the open end of a helical passage leading to the cylinder. In the modified construction shown in Fig. 5, the combustion chamber T is formed in a liner R which is closed by a plug S containing a helical passage S<2> by which the chamber communicates with the cylinder; the length of the combustion chamber is approximately equal to its diameter. A combustion chamber having a circumferential wall which is barrelshaped, frusto-conical, or bell-shaped and having end walls which may be flat, concave, or convex may replace the cylindrical combustion chamber.

The grooves 18 and ridges 22 are respectively equally spaced and may form continuous closed circles. The internal diameter of the outer tube 12 at the position of each ridge 22 is the same, being approximately equal to the outer diameter of the inner tube 14. The internal diameter of the outer tube 12 at the position of each valley 24 between the ridges 22 is also the same. The grooves 18 and the ridges 22 are complementary, as are the valleys 24 and the rings 17 between the grooves 18. The inner tube 14 may have at least two projections such as 20, which are widely spaced circumferentially. The projections 20 have substantially the same curvature as the valleys 24. The ridges 22 may also be interrupted circumferentially, but by an amount less than the circumferential extent of projections 20. The outer tube 12 may be made from paper, on which the grooves 18 and the ridges 22 are impressed. In particular, the outer tube 12 may be formed from laminated layers of paper strip wound in overlapped spirals and bonded with a water-releasable adhesive. The ridges 22 may be rounded, instead of sharply peaked, as in Fig. 3 (not shown). Between three and nine grooves 18 and corresponding ridges 22 may be provided, the ridges 22 being spaced to engage projections 20. In particular, eight grooves 18 and ridges 22 may advantageously be provided within a length of the outer tube 12 of approximately 0.5", and of depth approximately 0.01". The spacing of the ridges 22 may be about 0.07". The surfaces of tubes 12 and 14 may be covered in a lubricating material such as polyethylene oxide or other waxy material. The tubes 12 and 14 may alternatively be made of other sheet material, e.g. plastics, when the ridges 22, grooves 18 and projections 20 may be formed by pressure moulding, with or without heat.

Abstract: 1379528 Video signal transmissions GRUNDIG EMV 23 March 1973 [24 March 1972] 14241/73 Addition to 1348108 Heading H4F Video signals S 1  of a single television image are read in, at normal rate, into a first main store 2. Read-out device 3 reads out the main store, a single picture element at a time according to a predetermined pattern, e.g. an element from line 1 followed by an element from line 4 &c., and at a rate appropriate to the narrow bandwith of transmission line 5 and with each element stretched in time. The stretched and slowed rate video signal elements are received and sequentially stored in one element store 6. Second main store 7, scanned at the same normal rate as store 2, and in synchronism therewith (allowing for any propagation delays in line 5), has the contents of store 6 read into it at the current time in accordance with said predetermined pattern, with the reading in time being equal to the original element period. Due to the element stretching, i.e. the duration of stay of an element in store 6, slight asynchronism between the read out pattern of store 2 and the read into pattern of store 7 is allowed for.

Title: Electrolytic refining of aluminium
IPC: C25C3/24
Filed: 1938-05-13
Abstract: 503,578. Electrolytic refining of aluminium. COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTROMETALLURGIQUES ALAIS, FROGES, ET CAMARGUE. May 13, 1938, No. 14317. Convention date, May 14, 1937. [Class 41] In refining aluminium by the method in which the anode alloy, the electrolyte and the purified cathode metal constitute superimposed molten layers, the layer of electrolyte is corrected in composition and maintained at uniform depth by introduction in suitable proportion of material which has been purified by preliminary electrolysis in a three layer cell and decantation ; the introduction is effected without removing the cathode layer and without interruption of the refining. The invention is particularly applicable to a process as described in Specification 405,596, for example a process in which the electrolyte consists of 60 per cent barium chloride and 40 per cent of chiolite of composition 2AlF.3NaF. In the course of electrolysis the volume of electrolyte is reduced, its fluoride content approximates to the formula AlF.2NaF and a few per cent of barium fluoride is formed. An electrolyte containing 60 per cent barium chloride, 5-10 per cent sodium chloride, and 35-30 per cent AlF 3 .NaF is electrolysed in a feed tank, decanted and added to the refining cell. A proportion of the mixed electrolyte is then removed, to restore the bath to standard volume and returned to the feed tank where .the necessary salts are added to restore the composition necessary for correction of the refining baths. The use of purified aluminium as cathode layer in the feed tank is not necessary. Crusts of alumina deposited in the feed tank are removed from time to time.
